text: * Atropisomerism<br/>An energetic form of axial chirality. This form of chirality derives from differential substitution about a bond, commonly between two sp²-hybridized atoms.
  * Cis–trans isomerism<br/>Also referred to as geometric isomers, these compounds have different configurations due to the inflexible structure of the molecule. Two requirements must be met for a molecule to present cis-trans isomerism:<br/>1. Rotation within the molecule must be restricted.<br/>2. Two nonidentical groups must be on each doubly bonded carbon atom.
  * Conformational isomerism<br/>This form of isomerism is also referred to as conformers, rotational isomers, and rotamers. Conformational isomerism is produced by rotation about the Single bond.
  * Diastereomers<br/>These stereoisomers are non-image, non-identical. Diastereomers occur when the stereoisomers of a compound have differing configurations at corresponding stereocenters.
  * Enantiomers<br/>Stereoisomers which are nonsuperimposable, mirror images.
